  • Publication number: 20050140828
    Abstract: Composite ghost cancellation reference (GCR) signals that make available both a chirp and a PN sequence during the same vertical-blanking-interval (VBI) scan line in each successive field facilitate more rapid and efficient calculations of ghost cancellation and of equalization, on a continuing basis. A television receiver for use with such composite GCR signals includes circuitry for separating the chirp and PN sequence portions of the GCR signals from the remainder of the composite video signal, a ghost cancellation filter and an equalization filter connected in cascade to respond to the composite video signal and provided each with adjustable filtering weights, and a computer. Random-acess memory addressed during writing snatches the vertical-blanking-interval scan lines selected to include GCR signals. Sets of four successive ones of the selected scan lines are then additively and subtractively combined to separate the chirp portions of the GCR signals from a remainder of the composite video signal.

  • Publication number: 20050128704
    Abstract: An enclosure forms a plurality of tiers vertically stacked in a longitudinal dimension, each tier supporting two lateral stacks of printed circuit board cards. Each tier has an associated distribution plenum contiguous to a top longitudinal end of the tier and an associated exhaust plenum contiguous to a bottom longitudinal end of the tier. A pump receives air from a pump plenum, and pressurizes the distribution plenum with that air. The distribution plenum distributes the pressurized air through jets in the top of the tier, creating directed streams of cooling air. In the tier, the air flows longitudinally to the exhaust plenum on the bottom of the tier. The air laterally enters the enclosure via the pump plenum, and laterally exits the enclosure via the exhaust plenum.
